Abstract: A low-yield-strength steel shear panel damper (LYSPD) with 70% shear strain is developed and verified by static incremental cyclic tests in previous research. The mechanical properties and fatigue performance of the LYSPD deteriorate with the high temperature caused by high strain speed and internal friction in constant cyclic dynamic tests. To compare with the earthquake response wave, the deterioration mentioned above may be overestimated. Thus, this study is also seeking to develop a scientific understanding of the effects of heat and loading history on the LYSPD mechanical properties and fatigue performance. Several waves, the most prone to damage at each soil condition according to the DYMO simulation, are selected as dynamic test loading waves. The test results suggest that the heat and loading history have no influence on the LYSPD strength while they should to be taken into consideration of the fatigue evaluation.
